You don't actually care about *why* you have an lvalue of half type; you just
care that you *do*, and that you're trying to do an lvalue-to-rvalue conversion
on it. Just check whether the lvalue expression's type isHalfType() instead
of trying to enumerate all the syntactic cases that can give rise to it.
